问题描述

可以执行以下操作：

// Add two event handler for the button click event
button1.Click += new RoutedEventHandler(button1_Click_1);
button1.Click += new RoutedEventHandler(button1_Click_2);

但是如何为按钮的点击事件添加多个事件处理程序XAML？
感谢任何提示！

But how can I add multiple event handlers for the button's click event in XAML? Thanks for any hint!

推荐答案

您不能在XAML中订阅多个事件处理程序。然而，您可以通过订阅单个事件处理程序，然后从事件处理程序调用两个或多个方法来实现相同的效果。

You cannot subscribe more than one event handler in XAML. You can however achieve the same effect by subscribing a single event handler and then calling two or more methods from the event handler.

    private void Button_OnClick(object sender, RoutedEventArgs e)
    {
        ButtonOnClick1();
        ButtonOnClick2();
    }

    private void ButtonOnClick1()
    {
        //Do something...
    }

    private void ButtonOnClick2()
    {
        //Do something...
    }
